Subject: [PATCH] drm/i915:Move the code position to reduce the number of judgments
Date:   Thu, 25 Aug 2022 09:37:52 +0800
Message-Id: <20220825013752.120988-1-lvqian@nfschina.com>
Precedence: bulk

	If the kmalloc allocation is successful, the if is judged twice, 
	so I move the second judgment in to the first judgment.
